Conversion Table:
This conversion table gives an overview of the results obtained during the conversion.
Fluid no:
The fluid position in the instrument where the converted fluid is available.
Calibration date:
Date of the conversion.
The traceability of a calibration
VSL:
VSL is the National Metrology Institute of The Netherlands. VSL maintains and develops the Dutch measurement standards.
Bronkhorst Calibration Laboratory (BCL):
BCL maintains the measurement standards of Bronkhorst, which are calibrated by VSL.
Bronkhorst Production:
The calibration standards used in Bronkhorst's production process are calibrated by BCL.
The calibrated instrument
Type:
Is it a Flow meter or flow controller.
Serial number:
Serial number or order number.
Model number:
Type of instrument (customer model or Bronkhorst model).
Rated accuracy*:
The accuracy of this instrument specified under calibration conditions.
Calibration Standard
The calibration standard which is used during the calibration (example: Piston Prover, Rotor Meter, Turbine Meter, Reference Meter, etc.)
Type:
The calibration device which is used during the calibration, in this example a piston prover.
Serial number:
Serial number of the calibration device.
Certificate no.:
The certificate of the calibration device, which certifies the validity of the calibration standard
Uncertainty:
The reported uncertainty of measurement is based on the standard uncertainty multiplied by a coverage factor k=2.
Customer conditions
Fluid and conditions as indicated by customer.
Fluid:
The fluid (specified by customer)
Flow:
The flow range (specified by customer)
Pressure:
The pressure (specified by customer)
for which the instrument is calibrated for
Temperature:
The temperature (specified by customer)
for which the instrument is calibrated for.
Calibration conditions
The calibration conditions shows under which conditions the instrument is calibrated.
Fluid:
The calibration fluid.

Calibration and Conversion Results
Output signal:
The output signal of the instrument corresponding to the customer flow.
Customer flow:
The flow rate under the conditions as ordered by the customer.
Equivalent flow:
The flow rate under calibration conditions, which is equivalent to the customer flow rate under customer conditions.
